Leatherworking got updated! Mostly this is internal stuff that players would never notice, but it does mean that most items got descriptions based on quality, and there were a few changes with pelt requirements and weights, as well as syntax. While I was at it, I added a few items.

A note on pelt requirements - it used to specify that you needed a certain weight of material. This really doesn't make sense, because the different leather types (should) weigh different amounts. Now it specifies pieces, so please don't refer to weight requirements anymore IC.
